ANTISiKIDDING ATTACHMENT FOR VEHICLE-WHEELS.

Specification or Letters Fatent.

Patented Aug. 21, 1917.

Application filed August 24, 1916. Serial No. 116,678.

To all whom it may concern Be it known that I, J0me G. FRI-BERG, acitizen of the United States, residing at Maiden Rock, in the county ofPierce and State of Wisconsin, have invented certain new and useful Imrovemen-ts'in Antiskidding Attachments or Veh'ielediiheels, and I dodcclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to on nnti-skidding structure for vehicle wheels.

The primary object of the invention is to provide on anti-skiddingdevice for vehiclewheels which may be easily and readily attached to thewheel and removed thereirom.

Another object of the invention is to generally improve upon devices oi?this character by the provision of a device which will be simple,strong, durable and comparetively inexpensive in construction, elhcientand reliable in operation, and well adapted to the purpose for which itis designed.

With these and numerous other objects in view the invention consists ofcertain novel J, V c

' matures of construction and ,the combination and arrangement of partsas will be hereinafter fully described and claimed.

In the nccompenving drawings, in which similar reference cheriictersdesignate like parts throughout the several views,

Figure l is a side elevation of a portion oi a vehicle wheel, showing adevice constructed in nccordence with this invention;

Fig. 2 is a horizontal sectional view taken on the plane of the lineLP-2. of Fig. 1;

Fig. 3 is a transverse sectional view'talreu on the plane of the line3-- of Fig. 1; and

Fig. 4 is a plan view of the device deturehwl from, the vehicle wheel,the anti-skid chains being broken away.

'ti-l'erril'lg more particularly to thedrawings, :1, clamp is sl'lowncomposml of a pair olf crossed. members 1 end 2 which are pivotn'llyconnected at a point substantially midway of their ends by means of arivet 3. As clonrly shown by Figs. 1 and 2 of\ the drmvings, the innersides of the ends of the nn-mhcrs 1 and 2 are out away as at 4,

the cut away portions at the :uljncent ends, forming in con junctionwith each other suit able sockets for receiving the spokes of (1 vehiclewheel in connection with which the device is adapted to he used.

Secured to one of the sides of the mem bers 1 and 2 near one of the endsof the some are brackets 5 having apertures 6 therein, and, (intendingthrough said apertures is a chunpmg bolt 7, the threaded free end ofwhich receives a thumb out 8 forlocking or holding said members in theirclam )Bd position with respect to the spokes of the wheel to be morefully described hereinafter. It is to be, here noted that any otherequivalent me'ims for holding these members in their clamped positionmay be substituted for the brackets, clamping bolt, and nut shown in thedrawin s.

One of the ends 0? the members 1 and 2 are provided with apertures 9through which extend one of the ends oft. pair of anti-skid elements,here shown in the form of chains 10.- The other ends of the members 1 am2 are provided with notches 11 on the notched out portions 4 of theirinner sides for receiving the other ends of the chains 10 in a manner tobe'hereinui'ter described.

'lhe device is designed to be used. in connection with a vehicle wheelhaving it plurality of spokes S, a rim or felly R and a. tire T. Whenapplying it to the wheel, the clamp is disposed longitudinally betweentwo adjacent spokes S on the inner'side of the rim R and between theplanes passing through. the edges of the letter. It is obvious that whenthe device is thus applied the clm'nping nut 8 is removed from the bolt7- :md the letter is retrieved from the aperture 6 in the bracket 5carried by the member 2, and the members are swl; y on their pivot so asto bring their ends further spurt.

his will cause the clamp to be shortened, thereby allowing the some tobe easily inserted between the spokes. The a-nti skid chains 10 are thencarried substantially spirally around. the tire 'I crossing each otherat the trend of the some, andhcvin one of the links at their free endsdispose in the notches 11 at one of the cndsof the members i spokes ofthe same,

device may be adjusted to fit tires of different'diemetersiby en aqingthe proper links of the chains 10 wit t to notches 1L By having theanti-skid chains 10 carried spirally around the tire and crossed at apoint substantially coincident with the tread of the same, a moreeiiieient anti-skidding or gripping action upon the road or othersurface over which the vehicle is passing, will be cil'ected; However,it is to be understood that I do not wish to limit myself to carryingthe'ehains around the tire in this manner, as obviously they need not becrossed.

l 'rom'the foregoing description, taken in I connection with theacuompanyingdrawinga,

.the construction and operation of the device. will be readilyunderstood without a more extended ex ilnnation.

As numerous other changes in form, proportion, and in the minor detailsof construetion may be resorted to without departing from the spirit ofthis invention, do not wish to be limited to the construction hereinshown and described other than that set forth in the appended claims.

l elaim:

l. The combination with a vehicle wheel, a member extendinglongitudinally between two adjacent spokes of said wheel and beingdisposed entirely between the planes passing throiwh the edges of therim thereof, said member being provided with movable clamp membersengaging the opposite sides of said adjacent spokes, means for lockingsaid clamp meinlmrs in their spoke engaging positions, and an auti-skidelement connected to said number and extending around the tireol saidwheel.

3.. The combination with a vehicle wheel, of a clamp composed of a pairof crossed and pivotnlly connected members disposed on the inner side ofthe rim of said wheel and engaging. the opposite sides of adizicentmeans carried by said members for removably locking the same in theirclamped positions with res met to said spokes, and aillexible anti-skide ement, eonllidiid'dl to said clamp and extending around the ti re ofsaid wheel.

t. The rombination with a vehicle wheel, of a pair of crossed andpirotally connected members disposed on the inner side oi. the

in their clamped positions with respect to said spokes, and flexibleelements connected to the ends of said members and extending around thetread of the wheel.

4. The combination with a vehicle wheel, of a pair of clamp membersdisposed on the inner side of the rim of said wheel and engaging theopposite sides of two adjacent spokes of the same, means for removablyl'orking said members in their clamped positions with respect to saidspokes, said members bein provided with notches in the inner edges o oneof their ends, the open ends of said notches being closed by said spokeswhen said members are in their ehnnped ositions with respect to thesome, and llexil ile anti-skid elements having one of their endsdisposed in said notches, and their other ends connected to the otherends of said clamp members. I

5. A device of the class described comprising a pair of crossed andpivotally connected clamp members, means carried by said members forremovably locking the same in clamped positions, and flexible anti-skidelements connected at their of said members.

6. A. device oftbe class described comprisin 1 a pair of crossed andpivotally con neeted clamp members, anti-skid elements connected attheir ends to the ends of said members, of said members at adjacentends-thereof and having apertures therein, a clampin bolt exteming'through the apertures in said brackets, and a clamping nut disposedon the fine end of said belt for locking said mem hers in their clampedpositions.

In testimony whereof. 1 have hereunto set my hand in the presence of twosubscribing w tnesses.
